Gooby will oversee all ballpark operations at Safeco Field, including maintenance, engineering, sustainability, game day operations, grounds keeping, events, housekeeping and security.
He had spent the past 12 years in the Pirates organization, where he oversaw the team's Spring Training operations in Bradenton, Fla., as well as day-to-day operations of the Pirates' Class A affiliate in Bradenton.
Gooby was in charge of the Pirates' $10 million renovation in 2013 of McKechnie Field and Pirate City, the team's Spring Training and Gulf Coast League home and also oversaw all operations of the club's Dominican Republic complex in El Toro.
Before joining the Pirates, he spent seven years with the Dodgers as the general manager of the now-defunct Class A Advanced Vero Beach Dodgers in Florida.
While he's spent nearly 20 years working for Major League clubs, this will be his first opportunity to oversee ballpark operations in a Major League city.
Gooby, a native of Ipswich, Mass., is a 1998 graduate of Emerson College in Boston, where he earned a degree in communications and media studies.
